Wall Street’s most secretive trading firm has fired its first formal legal shot. On April 23, Jane Street Group filed a motion to dismiss the insider-trading lawsuit brought against it by Todd Snyder, the court-appointed administrator winding down Terraform Labs. It argued the complaint is an attempt to shift blame for a fraud that has already been charged, adjudicated, and punished.
The filing, entered on the docket of the U.S. District Court for the Southern District of New York and assigned to Judge Dale E. Ho, is the most substantive public response Jane Street has made since Snyder filed his original complaint on February 23. Until now, the firm had spoken only through spokesman statements, calling the suit “desperate” and “baseless.” Thursday’s dismissal motion is the legal version of those words.
“This case is an attempt by the estate of Terraform Labs to extract cash from Jane Street to foot the bill for a fraud that Terraform itself perpetrated on the market,” the defendants wrote in the filing. They also stated that the fraud tied to Terra has already been charged, adjudicated and punished, and we were not involved.
What Snyder Alleged — and Why It Matters
Snyder’s complaint is built around a single, damning sequence. On May 7, 2022, Terraform Labs quietly withdrew 150 million UST from the Curve 3pool—without any public announcement. Within 10 minutes, a wallet allegedly linked to Jane Street withdrew an additional 85 million UST from the same pool. The complaint calls this Jane Street’s largest-ever single swap and argues it broke the market’s confidence in TerraUSD.
The mechanism behind this alleged information advantage was a former Terraform intern named Bryce Pratt, who later joined Jane Street. Pratt allegedly established a private group chat—named “Bryce’s Secret”—through which material, non-public information about Terraform’s liquidity movements was funneled to Jane Street’s DeFi trading team.
The result, Snyder argues, was that Jane Street unwound “hundreds of millions” in crypto exposure at precisely the right time, protecting its book while the public was left holding the bag in a $40 billion collapse.
Jane Street’s Four-Part Dismissal Argument
The dismissal motion does not deeply engage with Snyder’s factual narrative of the “Bryce’s Secret” chat. Instead, it advances four independent legal arguments designed to kill the case before it ever reaches a jury:
- The fraud has already been prosecuted: Jane Street notes that the misconduct at the heart of the Terra collapse has already been adjudicated. Do Kwon pleaded guilty in December 2025 and is serving a 15-year federal prison term, and a jury found Terraform civilly liable for fraud. Allowing Snyder to pursue Jane Street now, the firm argues, is an attempt at “double recovery.”
- The information was public: Jane Street argues the insider-trading claims are “self-defeating.” The motion points out that Terraform’s transition to a new liquidity pool was publicly announced weeks before it occurred. The firm claims its largest trades were executed after damaging information about UST had already reached the public.
- The Wagoner Rule (In Pari Delicto): Jane Street invokes a powerful doctrine from federal bankruptcy law that bars a bankrupt estate from suing third parties to recover losses caused by the debtor’s own fraud. If Terraform’s collapse was caused by Kwon’s fraud, Snyder (acting for the estate) cannot legally blame Jane Street for making it worse.
- Jurisdictional limits: Jane Street contends Snyder failed to establish that the disputed trades—executed in decentralized Curve pools—actually took place on a U.S. exchange or within U.S. jurisdiction, a strict requirement under the Securities Exchange Act.
Three Lawsuits, One Collapsed Ecosystem
Thursday’s dismissal motion concerns the primary civil action (Case 1:26-cv-01536-DEH). However, Snyder has actually filed three separate actions against Jane Street, including two filed under seal in February 2026. This structure suggests Kirkland & Ellis is preserving different legal theories or categories of claimants.
The Jane Street litigation sits alongside a parallel $4 billion action against Jump Trading, filed by Snyder in December 2025, which alleges Jump secretly propped up UST before withdrawing its support.
Jane Street’s Wider Legal Exposure
The Terraform lawsuit is not Jane Street’s only major legal headache. In July 2025, India’s Securities and Exchange Board of India (SEBI) barred the firm from domestic markets, accusing it of manipulating index derivatives through aggressive high-frequency tactics at the expense of retail investors, resulting in a $566 million penalty.
This combination of the India ban and the Terraform lawsuit has made Jane Street—which generated $10.1 billion in trading revenue in Q2 2025 alone—unusually visible for a firm that has spent two decades operating out of the public eye.
What Happens Next
Snyder’s legal team at Kirkland & Ellis now has a set period to file an opposition to the dismissal motion. Judge Dale E. Ho will then schedule oral arguments or rule directly on the filings.
The central legal question is whether the Wagoner rule is strong enough to win a motion to dismiss. A dismissal motion is the lowest bar for a plaintiff; the court must accept all of Snyder’s factual allegations as true. Jane Street must prove that even if the 10-minute swap and the private chat happened, the lawsuit is still legally invalid.
If Jane Street fails to get the case thrown out, it moves to discovery. That is the real threat to the secretive trading giant. Discovery would force Jane Street to produce internal communications, trading records, and the specific timestamps of its UST swaps. A discovery process would put the inner workings of Wall Street’s quietest powerhouse on the public record.
